COLLABORATIVE RESEARCH: Interpluton Wall Rock Screens in the Sierra Nevada and their Bearing on Pluton Emplacement Processes

9814788科尔曼：在复合岩层中，分离单个侵入体的变质岩离散屏蔽物的保存是一个长期存在的、内在的有趣问题，它涉及到侵入岩浆如何获得空间。在屋顶吊坠方面已经做了相当大的努力，然而，墙壁岩石屏风也可能为侵入过程提供相当大的洞察力，但研究很少。这个由犹他大学、北卡罗来纳大学和波士顿大学的研究人员合作的项目将研究加利福尼亚州内华达山脉的插入式屏幕的例子，这些特征在那里得到了很好的开发和展示。结果应该有助于理解变质屏是如何形成的，以及它们可能为理解钚如何侵入地壳提供了什么见解。

9814788Coleman The preservation of discrete screens of metamorphic rocks separating individual intrusions in composite batholithes is a long standing and inherently interesting problem that relates to how space is mad available to intruding magma. Considerable effort has been directed at roof pendants however wall rock screens may offer considerable insights into intrusive processes as well, but have been little studied. This collaborative project between investigators from the University of Utah, University of North Carolina and Boston University will study examples of pluton screens in the Sierra Nevada of California, where these features are well-developed and displayed. Results should help understand how metamorphic screens form and what insights they might offer in understanding how plutons intrude the earth's crust.
